The truss rod is a thin, strong metal rod that runs along the inside of the neck. It is used to correct changes to the neck's curvature caused by aging of the neck timbers, changes in humidity, or to compensate for changes in the tension of strings. The tension of the rod and neck assembly is adjusted by a hex nut or an allen-key bolt on the rod, usually located either at the headstock, sometimes under a cover, or just inside the body of the guitar underneath the fretboard and accessible through the sound hole. Some truss rods can only be accessed by removing the neck. The truss rod counteracts the immense amount of tension the strings place on the neck, bringing the neck back to a straighter position. Turning the truss rod clockwise tightens it, counteracting the tension of the strings and straightening the neck or creating a backward bow. Turning the truss rod counter-clockwise loosens it, allowing string tension to act on the neck and creating a forward bow.


For example, if the note E (the open sixth string) is played over the A minor chord, then the chord would be [0 0 2 2 1 0]. This has the note E as its lowest tone instead of A. It is often written as Am/E, where the letter following the slash indicates the new bass note. However, in popular music it is usual to play inverted chords on the guitar when they are not part of the harmony, since the bass guitar can play the root pitch.
In acoustic guitars, string vibration is transmitted through the bridge and saddle to the body via sound board. The sound board is typically made of tone woods such as spruce or cedar. Timbers for tone woods are chosen for both strength and ability to transfer mechanical energy from the strings to the air within the guitar body. Sound is further shaped by the characteristics of the guitar body's resonant cavity. In expensive instruments, the entire body is made of wood. In inexpensive instruments, the back may be made of plastic.

Adding a minor seventh to a major triad creates a dominant seventh (denoted V7). In music theory, the "dominant seventh" described here is called a major-minor seventh, emphasizing the chord's construction rather than its usual function.[27] Dominant sevenths are often the dominant chords in three-chord progressions,[18] in which they increase the tension with the tonic "already inherent in the dominant triad".[28]
Modern pickups are tailored to the sound desired. A commonly applied approximation used in selection of a pickup is that less wire (lower electrical impedance) gives brighter sound, more wire gives a "fat" tone. Other options include specialized switching that produces coil-splitting, in/out of phase and other effects. Guitar circuits are either active, needing a battery to power their circuit, or, as in most cases, equipped with a passive circuit.
Minor chords arise as the tonic notes of minor keys that share the same key signature with major keys. From the major key's I-ii-iii-IV-V-vi-viio progression, the "secondary" (minor) triads ii-iii-vi appear in the relative minor key's corresponding chord progression as i-iv-v (or i-iv-V or i-iv-V7): For example, from C's vi-ii-iii progression Am-Dm-Em, the chord Em is often played as E or E7 in a minor chord progression.[24] Among basic chords, the minor chords (D,E,A) are the tonic chords of the relative minors of the three major-keys (F,G,C):
Jake Jackson's publications, as writer, editor or contributor, include The Beginner's Guide to Reading Music, How to Play Classic Riffs and Play Flamenco. As guitarist and songwriter he has been in a few bands, including Slice, The Harmonics and Starbank and has studied a form of Flamenco guitar. Although Jake has a range of fine guitars in his house his favourite music software is Sibelius and, having worked with Cubase for many years, is now moving over to Logic Pro.
Pickups are transducers attached to a guitar that detect (or "pick up") string vibrations and convert the mechanical energy of the string into electrical energy. The resultant electrical signal can then be electronically amplified. The most common type of pickup is electromagnetic in design. These contain magnets that are within a coil, or coils, of copper wire. Such pickups are usually placed directly underneath the guitar strings. Electromagnetic pickups work on the same principles and in a similar manner to an electric generator. The vibration of the strings creates a small electric current in the coils surrounding the magnets. This signal current is carried to a guitar amplifier that drives a loudspeaker.

Electric guitars can have solid, semi-hollow, or hollow bodies; solid bodies produce little sound without amplification. Electromagnetic pickups convert the vibration of the steel strings into signals, which are fed to an amplifier through a patch cable or radio transmitter. The sound is frequently modified by other electronic devices (effects units) or the natural distortion of valves (vacuum tubes) or the pre-amp in the amplifier. There are two main types of magnetic pickups, single- and double-coil (or humbucker), each of which can be passive or active. The electric guitar is used extensively in jazz, blues, R & B, and rock and roll. The first successful magnetic pickup for a guitar was invented by George Beauchamp, and incorporated into the 1931 Ro-Pat-In (later Rickenbacker) "Frying Pan" lap steel; other manufacturers, notably Gibson, soon began to install pickups in archtop models. After World War II the completely solid-body electric was popularized by Gibson in collaboration with Les Paul, and independently by Leo Fender of Fender Music. The lower fretboard action (the height of the strings from the fingerboard), lighter (thinner) strings, and its electrical amplification lend the electric guitar to techniques less frequently used on acoustic guitars. These include tapping, extensive use of legato through pull-offs and hammer-ons (also known as slurs), pinch harmonics, volume swells, and use of a tremolo arm or effects pedals.
All three principal types of resonator guitars were invented by the Slovak-American John Dopyera (1893–1988) for the National and Dobro (Dopyera Brothers) companies. Similar to the flat top guitar in appearance, but with a body that may be made of brass, nickel-silver, or steel as well as wood, the sound of the resonator guitar is produced by one or more aluminum resonator cones mounted in the middle of the top. The physical principle of the guitar is therefore similar to the loudspeaker.
Some piezo-equipped guitars use a hexaphonic pickup. "Hex" is a prefix meaning six. A hexaphonic pickup produces a separate output for each string, usually from a discrete piezoelectric or magnetic pickup for each string. This arrangement lets on-board or external electronics process the strings individually for modeling or Musical Instrument Digital Interface (MIDI) conversion. Roland makes hexaphonic pickups for guitar and bass, and a line of guitar modeling and synthesis products. Line 6's hexaphonic-equipped Variax guitars use on-board electronics to model the sound after various vintage instruments, and vary pitch on individual strings.

So with that in mind, would you like to learn the guitar on your own or with others? The choice is yours at Guitar Center. If you prefer one-on-one instruction, that's absolutely doable - in fact, you'll find our schedule to be very flexible. Of course, learning in a group is an excellent way to meet like-minded musicians with similar tastes and share ideas on how to improve one another's craft. Who knows, you might even leave a group guitar lesson with plans to start a band with your newfound musical companions. Either way, our group and private guitar lessons are very entertaining and informative.


I was lucky enough to meet Justin at the Guitar Institute during a summer school in 2004, and to have some private lessons with him afterwards.  He was the teacher who kickstarted my guitar career and persuaded me that I was ready to join a band.  That was 14 years ago and many dozens of gigs later.  I’m now just finishing a degree in Popular Music Performance.  Justin's online lessons are easy to follow and he has a manner about him which makes you believe that you can achieve.  Where he demonstrates songs, I have found his versions to be consistently more accurate and easy to follow than those of any other online teacher.  On this website you really will find all the skills and information you need to become an excellent musician.  Many thanks. Ian.
When you play a guitar, bass, ukulele, mandolin or any other instrument in this big family, it's the vibration of the strings that creates your sound. That's common knowledge, of course, but have you ever stopped to really think about the implications? It's all too easy to dismiss your strings as just another part of your instrument, but the truth is they're more like its heart - and since playing the instrument means touching its strings, they also have a huge impact on the way it feels to play. With all that in mind, it's easy to see why the choice of strings is such an important one: it can make a massive difference in every aspect of your instrument, especially playability and tone. Picking out a new set of strings involves a number of choices, and those will depend on the specific instrument, so don't forget to filter the lineup by selecting a category. In most cases, that'll leave you with an easy-to-browse range of options - although if you're a guitarist or bassist, you'll still have hundreds to look at... and it might take a little more filtering to narrow things down further. Choosing your gauges will go a long way, not to mention material, which ranges from nylon for classical guitars to phosphor-bronze in acoustics and steel, nickel or even cobalt for electric guitars. Another aspect of strings to consider in your decision is coating. Traditional coated strings have a smoother feel than their uncoated cousins and usually last much longer, but they're also wider and that can make them sound different. If you like the idea of coated strings, but don't want to give up the tone you get with uncoated ones, then check out Elixir and Cleartone strings: these two manufacturers have mastered the art of ultra-thin, "barely-there" coatings that behave more like traditional strings. We've only just scratched the surface of what's available in this section, and there's a lot to see no matter what instrument you play. Different materials and gauges, coated or uncoated - it's up to you. You can buy your strings one at a time, go for a set or even stock up with multiple sets of strings at once. Still not sure where to begin? Try starting with the top-selling and best-rated strings and go from there. Finding the perfect set will probably take some experimentation, but there's no better guide than other musicians to get you on the right track.
When you’re learning a new chord, make the shape and leave it on the guitar for about thirty seconds. Then remove your hand, shake it out, and make the chord shape again. It may take some time for you to make the chord shape again, but that’s okay because you’re working on your muscle memory. Repeating this process a few times is a great way of memorizing your chords.
Though they may not be as exciting of a topic as instruments or amplifiers, choosing the right type of strings for your guitar is incredibly important. Guitar strings have different responses and different feels, and when the right type of string is used it’s a huge asset to your playing. Likewise, when the wrong type of string is used it can be incredibly detrimental.
Ask any veteran musician, and they'll tell you that the early stages of learning a musical instrument go by a lot smoother when you're having fun. For this reason, Guitar Center strives their hardest to ensure every guitar lesson they offer is fully-engaging and an absolute blast for everyone involved. Whether you're into the warm, natural sound of an acoustic guitar or have aspirations of blowing out ear drums on the biggest stages in town, GC's guitar lessons are designed so that players of all ages, skill levels and tastes learn the chords and scales they need to know (and want to know) in a comfortable environment.

With just a little more music theory, you can learn to write simple songs with the chords you've just learned. The song would be in the key of C major (C, D, E, F, G, A and B). You can use the major chords for the I, IV and V notes and the minors for the II, III and VI notes. That means you can play a chord progression which uses all of the chords you've learnt, if you want to.
I would especially like to stress the gentle approach Justin takes with two key aspects that contributed to my development as a musician - music theory and ear training. Justin has succeeded in conveying the importance and profoundness of understanding music both theoretically and through your ears while maintaining a simple and accessible approach to them, all while sticking to what is ultimately the most important motto: 'If it sounds good, it is good'.
While four years old is a little young for formal guitar lessons, it's not too early to begin teaching your child musical concepts that will be important once they are old enough for guitar instruction at School of Rock. Your 4-year-old can participate in the Little Wing music program to learn fundamental concepts through fun, dynamic musical activities. 
I strongly recommend beginner guitar players to use the Uberchord app (click for free download) for practicing chord progressions and chord changes, and use the real-time feedback to improve your playing skills. While, I’ll help you expedite the process of grabbing chords confidently on the neck and get you on your way to playing along expertly with your favourite band, or better yet, running a band of your own.
